IMPROVEMENT-IN METALLIC FENCES.

Specification forming part of Letters PatentNo. 84,062, dated November 17, 1868.

To all whom it may concern Beit known that I, MICHAELv KELLY, of

useful Improvements in Metallic Fences 5' f and I Adol hereby declare that the following is' a full and exactdescription thereof.u

In the patent issued to me dated 11th day yof February, 18681 have described a fence composed offround wire carrying-thorns orv pointedpieces strung thereon, the wires passing through .the thorns. In my present invention the .thorns are thrust through the es, thereby making a fence equally desirf abiewith less labor.

. Mynew form can be very readily made bymachinery which shall draw along the wire,

perforate it, insert the thorn, and confine it.

"My former construction, 'though analogous thereto in some important points,A involved difficulties in its construction which this avoids.

` .It is impossible to pull theiength of wire through the thorn by machinery, or even by hand, except very slowly and vtediously. A

5I will proceed to describe what I consider the best means'of carrying out my invention.

. .The accompanying drawings form a part of this specification.

Figure l is aplan view of a portion of the wire with the thorns in place, the wire being dat and presentededg'e upward. The thorns are represented nearer together than I propose to make them in general practice. I esteem six inches a good distance; but this distance may be varied indefinitely.

Fig. 2 is a side view of the same, representing the wire after the holes have been marked or' slightly cut through by a sharp instrument before they have been spreadopen. A

Fig.,3 represents the same afterfthe -holes have been spread open ,by the introduction of a: pointed punch or the like, and the `thorns havebeeninserted, but not secured. l Fig. d representsthe same after 4the thorns" have been firmly secured by compressing the wire and the `thorn forcibly together by a blow of a hammer or otherwise. Fig. 5is a cross-section on the line S S in Fig'. 4.

Fig. 6 is a -plan view of. a modification, in which the thorn is made in the form of a common tack, but with the dies vin which the tack equal to the thickness of the wire. o This con- ,struction allows the thorn to be locked in place with but a very gentle compression of the wire upon it.

Fig. 7`showsthe tack separately before its connection with the wire` Fig. 8 represents a thorn prepared from common round wire, cutting it off obliquely in the same manner `in which the thorn is prepared in Figs. 3, 4, and` 5, but griped in ma chinery, (not represented,) so as to compress it near the middle and adapt it to be morereadily locked. 1

Similar letters ot .reference indicate correspending parts in all the figures.

i The tints employed do not necessarily indicate differences of material. The material of the'whole may be iron tinned or otherwise is a'iiat wire, rolled or otherwise produced in is griped so formed and operated as to conl-V4 press or indent the tack for a space aboutr from 'fixing the main wire within the thorns,

considerable lengths in the ordinary manner.

Through this wire I produce holes a by punching or otherwise, by hand or machinery. B are thorns, made by hand or by machinery,

pointed at each end. They are thrust into the holes a, and are there retained by compressing the'wire upon, and partially into, the same.

I can set the thorns in o my wire after the fence is erected, if necessary in'any-case; but

hand or by machinery before 'the' wire has left the manufactory. I prefer to ibrnrthe'thorns of metalwhich is a little softer than the wire, so that in theact of compression the thorns I esteem it preferable to setthe thorns by will yield and be firmly locked without much drawing or diminishing the thickness of the main wire at that point. By cutting oithe loss of material.

The several other modifications represented `thorns B very obliquely, as represented, I in sure a good point at each end without labor or My present invention avoids the serious dif- ,iiculty incident to the making of'the ,fence de- ,"scribed in my previous patent.

Ain, as ,will be obvious.

2 v l sentez lv'- t will he obvious that in xing thorns on great lengths of. wire, according to Klny previous patent,- cneh thorn required to be moved 0 1' slid along a great distance on the Wire. .l can ineke my present fence in any length desired lwitlu'mt encountering any corresponding diicult'y.

'- For'most purposes, however, I :propose to :manufacture -'the tliornyjmnterial 'in short lenlgthsfrom twelve to sixteen or twenty feet,

AHaving now fully described my invention, what I olalm'as new, and desire to secure by Letters Patent, is

The eonstruotiou of'- thorny fence by fixing the thorns B Ain lholes 'in the wire vALin the manner and foi' the purposesherein set-forth.` I i In testimony whereof I have' hereunto set my naine iri presence .of two silbserblng w1t uesses. y
